This invention relates to ironing pads for steam pressing machines and particularly to pads Vin the form of awire mat or brush having a steam permeable body portion or back.

By applying such ironing pads to steam pressing machines, the ironing effect of the machine can be improved so that the cloth becoming shiny is avoided and the work expedited.

With iro-ning pads of this kind, it is already known, to secure the wire bristles of the brush to a relatively thick body portion of fabric which, however, keeps back the steam penetrating into the same. As the wire matting is placed in the machine underneath the upper ironing pad, this matting is only adapted for application to pressing machines wherein the steam is admitted through the lower ironing pad, whereas to the most part of the existing pressing machines with steam admission through the upper ironing pad this matting is not applicable.

For this reason it has already been proposed to use wire mesh for the body portion of the pads, said portion comprising parallel woven-in supporting wires around each of which bent up wire elements pointed at each end are passed.

Due to the fact that these wire elements or bristles are passed around only a single wire woven in the body portion of the matting, all of these short wire elements can turn about the long supporting wires through an angular extent up to 90, as the wire elements are not secured against such turning movements. Furthermore, turning down of the pointed bristles in the direction perpendicular to the rotational displacement may also occur, as the portion of the wire elements passed round the supporting wires is very short and the elements are secured only by a zig-zag shaped wire interwoven with the supporting wires in the back of the matting which manner or" securing is, however, entirely insufcient. Moreover, as the wire elements, during' a pressure exertion on the points of the same, come to bear rearwardly only against a wire of the back of the matting which extends pari allel to the wire around which the element is invention distinguishes from the above-'described known matting by the feature that the bent` up wire elements are secured to parallel support-V ing wires comprised by. the Abody portion of `the pad by passinga portion .of their length partly above and partly below some of said supporting wires and arranging the wire elements in laterally relatively oiset relationship with the individual elements close to each other, so that open spaces are formed between groups of elements.

Due to the arrangement of passing the wire elements partly above and partly below the supporting wires of the body portion and adjacent elements being close to each other, the latter are very securely held on the body portion by being so effectively supported as to be prevented from turning down. The wire elements are further secured in position by the yokes of adjacent wires contacting each other along almost their full lengths. Thus, by means of the invention a much greater resistivity of the wire elements or bristles of the wire pad than usual is obtained, while at the same time the pad is highly permeable to steam. Furthermore, this pad is distinguished by simplicity of construction.

In the accompanying drawing a constructional form of the invention is illustrated by way of example only, in which Fig. 1 shows a sectional view of the pad, and

Fig. 2 a plan view thereof.

On a body portion made of parallel wires 1 U-shaped short wire elements each comprising two upstanding legs 2 and an intervening yoke 3 are held, the middle portion of the yoke 3 being passed above two wires 1 and each end portion of the yoke extending below a further wire 1A of the body portion. The legs 2 are inclined to the direction perpendicular to the body portion in such manner that their ends are situated perpendicularly above the two outermost wires 1 holding the respective wire elements 2, 3. The elements 2, 3 are successively laterally offset relatively to each other by one wire 1 of the body portion and lie against each other snugly, the individual short wires thus mutually securing each other in position and the wires 1 in turn are also held in position and a uniform distribution of the projecting ends of the short wires is obtained. The groups of succeeding wire elements 2, 3 form oblique rows spaced apart by a certain distance. Between the wires 1 interstices of a width corresponding to this distance are formed through which, when the pad is used in steam pressing machines, the steam can pass. The ends of the wires 1 of the body portion of the pad arev interconnected by a marginal iron band 4, the wire elements 2, 3 thus being prevented from dropping off laterally.

I do not limit myself to the particular size, shape, number or arrangement of parts as shown and described, all of which may be varied without going beyond the scope of my invention as shown, described and claimed.

What I claim is:

1. In an ironing pad for steam pressing machines, a steam-permeable wire body member supporting wires With their middle portions passing above the respective supporting wires and the portions of each element adjacent to its middle portion each passing below one of said supporting wires, adjacent elements being in contact with each other and arranged in groups on said supporting wires in laterally oiTset relationship forming open spaces between themselves for the passage of steam.

3. In an ironing pad for steam pressing machines, a steam-permeable wire body member comprising parallel supporting wires and laterally projecting Wire elements secured to said parallel supporting wires with their projecting portions inclined to the plane of the latter and with a portion of their length passing above and another portion below some of said supporting wires, adjacent elements being in contact with each other and arranged in groups on said supporting wires in laterally oiTset relationship forming open spaces between themselves for the passage of steam.
